Description

Technical Field

[0001] This utility model relates to the field of chip dispensing technology, specifically a dispensing device for chip manufacturing. Background Technology

[0002] Dispensing, also known as coating or dripping, usually refers to applying electronic adhesive or other liquids onto a product to fix it or smooth its surface. In industrial production, chips are numerous and small in size, and it would take a long time for workers to apply dispensing directly by hand. Therefore, a dispensing device for chip production is proposed.

[0003] Chinese patent publication number CN220861885U discloses a chip dispensing device, filed on September 15, 2023. This patented technology integrates heating and amplification. A chip with gold wires bonded to it is placed on a heating plate, and the position of the gold wires is observed using a binocular microscope. A handheld dispensing head allows for precise dispensing. Turning on a button activates the heating plate, causing the adhesive on the chip to solidify, greatly simplifying the operation and improving efficiency. However, in the above-mentioned device, because the chip position is not fixed, the contact force between the dispensing head and the chip surface during dispensing may cause the chip to shift, affecting the subsequent determination of the dispensing position. Therefore, the inventors provide a chip dispensing device for chip production to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a dispensing device for chip manufacturing, which achieves the effect of positioning and fixing chips.

Chip bodies are evenly arranged on the top of the conveying device. A positioning mechanism is provided on the right side of the conveying device. The positioning mechanism includes a fixed plate fixedly connected to the right side of the right support plate. A horizontal bar that can move left and right is provided on the top of the fixed plate. A T-shaped plate is fixedly connected to the left side of the horizontal bar.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This chip dispensing device for tablet computer production starts the first cylinder with an external power supply. The output end of the first cylinder drives the crossbar to move to the left. At the same time, the transmission of gears and toothed plates drives the rotating rods on both sides to rotate inward until the left side of the T-shaped plate is in contact with the right side of the chip. After the L-shaped plate rotates, it is completely in contact with the other three sides of the chip, thereby achieving the effect of positioning and fixing the chip.

[0014] Furthermore, this chip dispensing device for tablet computer production utilizes an external power source to activate a second cylinder. The output of the second cylinder extends downwards, slowly stretching the loose connecting hose and moving the glue cartridge to a suitable position on top of the chip. Then, the external power source activates a third cylinder, whose output moves downwards, driving a piston downwards. This dispensing of the glue from the cartridge onto the chip through the dispensing head, achieving the desired chip dispensing effect. Simultaneously, by controlling the piston's movement distance with the third cylinder, the piston's upward and downward movements are consistent, ensuring a consistent glue dispensing volume each time, achieving a quantitative glue dispensing effect. Additionally, when the third cylinder's output moves the piston upwards, the negative pressure inside the glue cartridge replenishes a quantitative amount of glue from the loading cylinder through the connecting hose, thus achieving a quantitative glue replenishment effect within the cartridge.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Example 1

[0022] like Figure 1 As shown, a dispensing device for chip production includes a pair of vertically arranged support plates 10, which are arranged parallel to each other, one on the left and one on the right. A conveying device 11 is connected between the inner sides of the two support plates 10. The conveying device 11 mainly includes a conveyor belt that can move intermittently from front to back. Chip bodies 12 are evenly arranged on the top of the conveying device 11. A positioning mechanism 20 is provided on one side of the conveying device 11. In this embodiment, the positioning mechanism 20 is located on the right side of the conveying device 11.

[0023] refer to Figure 1-3, in this embodiment, the positioning mechanism 20 includes a fixing plate 201, which is horizontally fixedly connected to the upper top surface of the right support plate 10. A vertically arranged positioning plate 202 is fixedly connected to the right side of the top of the fixing plate 201. A first cylinder 203 is vertically and fixedly connected to the left side surface of the positioning plate 202. The output end of the first cylinder 203 is fixedly connected to a cross bar 204, and the direction of the cross bar 204 is perpendicular to the direction of the first cylinder 203. A T-shaped plate 205 is fixedly connected to the left side of the cross bar 204, and the central part on the left side of the cross bar 204 is perpendicularly connected to the vertical bar in the T-shaped plate 205. Rotating rods 207 are respectively rotatably connected to the front and rear sides of the cross bar 204, and the rotating rods 206 can rotate horizontally. The bottom of the rotating rod 206 is fixedly connected to an L-shaped plate 208.

[0024] Specifically, mirror-symmetrical tooth plates 209 are respectively fixedly connected to the front and rear sides of the positioning plate 202; gears 210 are respectively fixedly connected to the bottoms of the two rotating rods 207, and the outer sides of the tooth plates 209 are meshed with the corresponding gears 210.

[0025] At the initial stage, as Figure 3 shown, the conveying device 11 is in an intermittent state, the rotating rods 206 and the cross bar 204 are in the same straight line direction. The front rotating rod 206 extends forward in the same direction as the cross bar 204, and the rear rotating rod 206 extends backward in the same direction as the cross bar 204.

[0026] If this embodiment is to be started to work, it is necessary to connect to an external power supply and start the first cylinder 203. The output end of the first cylinder 203 drives the cross bar 204 to move leftward. Since the gears 210 and the tooth plates 209 are meshed, the leftward movement of the cross bar 204 will drive the two gears 210 to rotate inward; at the same time, the transmission between the gears 210 and the tooth plates 209 will drive the two rotating rods 206 on both sides to gradually rotate inward, so that the rotation angle gradually reaches 90 degrees, and the two rotating rods 206 in the same straight line gradually reach a parallel state until the left side edge of the T-shaped plate 205 fits the right side edge of the chip, and the L-shaped plate 208 rotates in the same direction as the corresponding rotating rod 206. After rotation, the two L-shaped plates 308 on both sides are combined into a "冂" shape and completely fit on the front, left and back three side edges of the chip, as Figure 2 shown, so as to achieve the effect of positioning and fixing the chip.

[0027] Then, glue is applied to the appropriate position of the chip. After the glue application is completed, the output end of the first cylinder 203 contracts to drive the cross bar 204 to move rightward. At the same time, the transmission between the gears 210 and the tooth plates 209 will drive the two rotating rods 206 on both sides to rotate outward respectively, so that the two parallel rotating rods 206 gradually become in the same direction as the cross bar 204, that is, the two rotating rods 206 and the cross bar 204 are in the same straight line direction; the L-shaped plate 208 and the T-shaped plate 205 also leave the surface of the conveyor belt, so as not to interfere with the subsequent conveying of the chips.

[0028] refer to Figure 1 , 4 The top of the conveying device 11 is provided with a dispensing mechanism 30. The dispensing mechanism 30 includes a turning plate 301 fixedly connected to the top of the left support plate 10. The turning plate 301 is formed by vertically connecting a vertical plate and a horizontal plate from bottom to top. A second cylinder 303 is fixedly connected to the bottom of the horizontal plate. A glue cylinder 304 is fixedly connected to the output end of the second cylinder 303. A piston 308 is slidably connected inside the glue cylinder 304. A dispensing head 305 is fixedly connected to the bottom of the glue cylinder 304.

[0029] Specifically, a loading cylinder 302 is fixedly connected to the top of the turning plate 301, and a connecting hose 306 is fixedly connected to the right side of the loading cylinder 302. The connecting hose 306 passes through the horizontal plate and is fixedly connected to the rubber cylinder 304. A third cylinder 307 is fixedly connected to the top of the inner side of the rubber cylinder 304, and the output end of the third cylinder 307 is fixedly connected to the piston 308.

[0030] In this embodiment, a one-way valve 309 is installed on the connecting hose 306, and a one-way valve 309 is also installed on the dispensing head 305 (not shown in the figure); the one-way valve 309 on the connecting hose 306 only allows the connecting hose 306 to input adhesive into the glue cartridge 304, while the one-way valve 309 on the dispensing head 305 only allows the adhesive inside the glue cartridge 304 to be discharged.

[0031] In operation, the second cylinder 303 is activated by an external power source. The output of the second cylinder 303 extends downwards, slowly pulling the loose connecting hose 306 downwards, moving the glue cartridge 304 to a suitable position on the top of the chip body 12. Then, the third cylinder 307 is activated by the external power source. The output of the third cylinder 307 moves downwards, causing the piston 308 to move downwards, thus dispensing the glue inside the glue cartridge 304 onto the chip body 12 through the dispensing head 305, achieving the effect of dispensing glue onto the chip body 12. Simultaneously, by controlling the movement distance of the piston 308 by the third cylinder 307, the piston 308 moves consistently up or down each time, ensuring a consistent glue dispensing amount from the dispensing head 305 each time, achieving a quantitative glue dispensing effect. Furthermore, when the output of the third cylinder 307 moves the piston 308 upwards, the negative pressure inside the glue cartridge 304 replenishes a quantitative amount of glue from the filling cylinder 302 through the connecting hose 306, thus achieving the effect of quantitative glue replenishment within the glue cartridge 304. After the dispensing is completed, the output end of the second cylinder 303 moves upward, thereby driving the glue cartridge 304 back to its original position.

[0032] The working principle of the present utility model is as follows: When the conveying device 11 is in the intermittent period, the external power supply is connected and the first cylinder 203 is started. The output end of the first cylinder 203 drives the cross bar 204 to move leftward. At the same time, the transmission between the gear 210 and the toothed plate 209 drives the two side rotating rods 206 to rotate inward, so that the two rotating rods 206 gradually rotate from the same straight line direction to a parallel state until the left side of the T-shaped plate 205 abuts against the right side of the chip. The L-shaped plate 208 rotates in the same direction as the corresponding rotating rod 206. After rotation, the two side L-shaped plates 308 are combined into a "冂" shape and completely fit on the front, rear and left three sides of the chip, so as to achieve the effect of positioning and fixing the chip. Then, glue is applied to the appropriate position of the chip. After the glue application is completed, the output end of the first cylinder 203 contracts to drive the cross bar 204 to move rightward. At the same time, the transmission between the gear 210 and the toothed plate 209 drives the two side rotating rods 206 to rotate outward, so that the two parallel rotating rods 206 gradually become in the same direction as the cross bar 204. The L-shaped plate 208 and the T-shaped plate 205 also leave the surface of the conveyor belt.至此,芯片的点胶工序完成。
